gsessionId always null in google response.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. execute any method of CalendarService.cls (for example getCalendarByTitle).

What is the expected output? What do you see instead?
You get an exception "list index out of bound" because in the line 189 of 
GoogleService.cls, the string gsessionid is not in the header.

What version of the product are you using? On what operating system?
last version on summer 13 and winter14 (tested in both and it fails)

Please provide any additional information below.
the login works great, it's after the login when it crashes.
I think google has changed the response url. Is there any workaround?
